* There are two new entitlements related to this, which you ask Apple to give you if you're a dating app.
* Once you get the entitlements, you need to create a new version of your app (it cannot be the same as your international one) that will ship exclusively in the Netherlands with that entitlement.
* Details of how this entitlement work will come at a later date.
* Apple will still charge a commission on these purchases, the details of which will also come at a later date.
* It is your privilege/responsibility to conflict resolution with regards to refunds and such.
In essence, Apple complied with the law in the narrowest terms they could, but they did indeed change things and I suspect many companies will go through this process even if it's made somewhat inconvenient. I guess what remains to be seen is if these entitlements slowly get rolled out in other countries as they also enact legislation to require it.
